环氧化天然橡胶玻璃化转变温度与环氧化程度的关系
The relationship between T g and B of epoxidized natural rubber
【摘要】 根据Van Krevelen 等提出的一些高聚物物理参数加合性原则,推导了环氧化天然橡胶(ENR) 的玻璃化转变温度(Tg) 与环氧化程度(B) 的关系,并根据经验公式计算了不同环氧化程度ENR 的Tg 。
【Abstract】 The relationship between glass transition temperature (T g) and epoxde contents(B)of Epoxidizede Natural Rubber(ENR) was deduced according to the calculation law on some physical constants of polymers suggested by Van Krevelen and others.And a serial of T g values of ENR with different B was calculated by means of Hayes’s experience equation.
